RD Sharma Solutions Class 12 Increasing And Decreasing Functions

RD Sharma Solutions Class 12 Chapter 17

Differentiation will be used to find whether a function is increasing or decreasing.

Interval and nature of function

Theorem: Let f be continuous on [a, b] and differentiable on (a, b) Then:

  • f is increasing in [a, b], if f’ (x) ≥ 0, ∀ x ∈ (a, b)
  • f is decreasing in [a, b], if f’ (x) ≤ 0, ∀ x ∈ (a, b)
  • f is a constant function in [a, b] if f’ (x) = 0, ∀ x ∈ (a, b)
